the main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. the obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...

in this work, novel thin film composite membranes (tfcs) of poly (ether-6-block amide) (pebax-1657) on a polyvinyl chloride (pvc) ultrafiltration membrane as support were prepared using inclined coating method for co2 separation. investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), and also, t...

In this work, the correlation between SiO2 deposition thickness and hydrogen content is discussed effect of layer on properties synaptic InGaZnO (IGZO) TFTs analyzed. Three types IGZO thin-film transistors (TFTs) were fabricated with different gate insulators, as a insulator was investigated. XPS analysis confirmed that in Al2O3 layers increased during step for all depth regions. Hydrogen injec...

In this paper, ZnO thin film is deposited on slide glass substrate using the sol-gel process. Presenting well-defined orientation of ZnO thin films Nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (MEA), de-ionized water and isopropanol alcohol. The annealed ZnO thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....

Post-crystallization heat-treatment of metal-induced laterally crystallized polycrystalline silicon thin film using YAG solid-state laser is characterized. It is found that both the material quality and the TFT performance are related to the laser-treatment condition. The amorphous silicon fraction remaining in the polycrystalline thin film can be reduced and the performance of the thin-film tr...

A calcium fluoride thin film co-doped with Yb3+/Tm3+ was deposited on Si substrates by the spin-coating method using trifluoroacetic acid as a fluorine source. The scanning electron microscopy (SEM) image of the sample showed that a thin film with some cracks was formed. After annealing, the cracks disappeared, and the film became thinner. The roughness of the thin film was about 150 nm, which ...
